(x) sin x + Q(x) cos x, where P and Q are functions of x to be determined. Differentiation of (1) gives. (2) x? cos x = P' sin x + P cos x + Q' cos x-Q sin x. tan x = sin x cos x . The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x. Mar 19, 2023 ... We find the derivative of cosx^2 with the chain rule, cos^2x with the chain rule, and cos2x also with the chain rule. Nov 16, 2010 ... Thanks to all of you who support me on Patreon.
